Default pressure is not rising in compression stroke..
Posts: n/a
i'm simulating the compression stroke of ic engine in CFX 11. at the end of suction stroke the mass in the cylinder was around 11 mg. but i'm getting pressure only 22 bar at the end of compression stroke. experimentaly it is around 32 bar. in CFX 10 for the same case it came around 36 bar. why the pressure is not rising in CFX 11???
